llIEANS FOR MOUNTING AND CUTTING LABEL-HOLDER CHANNELS.

Application filed July 14, 1924 Serial No. 725,928;

To all whom may concern.-

Be it known that l. JAMES Coons, a citizen 0f the United States, residing at Omaha, in the county of Douglas and State of Ne braslia, have invented certain new and use ful lnnprovcments in Means for Mounting and Cutting Label-Holder Channels, of which the lt'ollowing is a specification.

My invention relates to metal cutting and forming devices, and it is the object thereof to provide a simple, compact and efficient mechanism for applying label-holding channels to the wooden blocks or mounts commonly used for rubber hand-stamps. .My present. invention is intended particularly for use in connection with label-holders of the character described in Letters Patent No. 1511,0253, issued to me October, 7, 1924, with which the label-holding channel-bar is formed in long pieces provided at uniform intervals with integral tongues adapted to be driven and clinched in wood or like material. A particular object of my invention is to provide a device adapted to sheanoi'i' from a channel-shaped bar sections or pieces which have been previously affixed to a block,

the shearing operation serving to close or crimp down the flanges of the channel-bar at the end of the sheared-off piece, while the channel is kept open at the end of the main piece.

Mechanism embodying my invention is illustrated in the accompanying drawings, in which Fig. 1 is a front view thereof, Fig. 2 is a partial longitudinal section'on the line 22 of Fig. '7, Fig. 3 is a detail plan View of the holder-block, Fig. l; is a side View of the same, partially in section on the line t t.

of Fig. 3, Fig. 5 is a detail transverse sec tion of the label-holding channel-bar, Fig. (3 is a. plan View of the entire mechanism, and Fig. 7 is a fertical section on the line 7-? of Fig. 6.

In the structure illustrated I provide a metal base-plate 8 adapted to be attached by screws 9 to a table or bench, and upon the central part of said base-plate, extending longitudinally thereof, is secured the anvilbar 10. A hammer or bumper-bar 11 is-arranged above saidanvil-bar, so that its lower surface extends parallel therewith, said bumper-bar being carried at the lower end of a vertical rod or stem 12 which passes slidably through a guide 13 on a standard let. The base of the latter is secured to the plate 8 behind the central part of the anvilbar, and the front face of the standard has a flat guide-surface against which the rear s de of the bun'iper-bar rests slidably; A

thereof. The lower portion of the stand d 14 has an opening 18'there1n, for a purpose which will presently appear.

The holder-block 19 is secured to the base 8 at one end thereof, said holder-block being at right angles to the anvil-bar and slightly spaced from one end thereof. Adjacent'to and in alinement with the anvil-har, the holder-block is recessed to receive the mandrel 20, which is secured in the recess by means of a screw 21. At the inner end thereof, adjacent to the anvil-bar, the man drel has laterally projecting flanges 22 adapted to fit sl'idably within the U-shaped side-flanges B of the label-holding channelbar A, the sectional form of which is clearly shown in Fig. 5. Said flanges are of full width at the inner end-face of the mandrel, adjacent to the anvil-bar, and for a short d stance back ii'roin said end-face, thence beingbeveled inwardly and terminating at the sides of the niandrel b'ody. intermediate its ends, as shown. clearly in Fig. 3. The luilder-bloch 19 is grooved about said flanges 22 to provide a suflicient space for the flanges ll of the channel-bar A to pass slidably between the sidcs'of the groove and said n'iandrel-fianges at the ends where said llanges'are of full width, the grooves 23 of the block being extended entirely across the same to the outer side. The upper surface of the mandrel is at the same level as the upper surface of the anvil-bar, and the width of the anvil-bar is such that the inturned edges of the flanges B may fit slidably against the s des of the bar. I

in the use of the mechanism, a long piece of the channel-bar A is engaged with the mandrel by first laying the end of the channel-bar upon the outer or unfianged end of .flanges pass about the mandithe mandrel, so that the flanges B lie Within the grooves 23 in the block 19;"an'd then sliding the channel-barinwardly sothat its el-flanges 22. By continued inward slidingmovement of the channel-bar, it emerges fromthe end of the mandrel and passes out overthe anvilbar, the flanges B overhanging at the sides thereof; and the tongues C of the channel- 1 may extend out over the-anvil-bar.

guide-posts, so as being coil springs 27 disposed posts between said clamp-blockhnd holder above the mandrel, the purpose of said *grooyebeing'to providecleara'nce for the.

C of the channel-bar when suchbar extending upwardly 'as indicated in Figs. land 2. Inthe anv1l-bar there are a series of holes 38 indicated in Fig. 1, adapted to receive a gageT-pi1r39,aga1nst which the end of the channel bar A maybe engaged to limit the length of said bar *hich Said holes es'are positioned'nearer to one side of the anvil-bar thanto the'other; as indicated in Fig. 6, so astobe engagedby' aportion of the channel-bar atone side of the perforations therein formed by the punching out of the tongues O. I 7

Tile hollerblock 19 is reniovably secured to the base-plateSby means of asc'rewfil, the block being prevented from I turning about the axis of said screw by apair of vertical guide-posts which are fixedly mounted upon the base, andwhiclrextend through holes in the block adjacent to the ends thereof. The block is slidable upon'said to be readily removed from the base after taking out the screw On the upper portions of the guide-posts is slidably mounted the clamp-block 26, there a1- ound the block, I saideprings extending intd ccun't'er bores'or cylindricalrecesses formed in the nected with a tension tending downwardly flush with or in the same vertical .tion of the shear-plate is spaced from an best shown in Fig. '2.

mally in the diagonalposition shown in Fig. 7, being provided at ts adjacent faces of the blocks concentrically with the posts. The springs 27*are so proportioned as to homel hold the clampbloch in the raised position shown iii Figs. 1, 2 and 7, but are compressible"so'as to lie wholly Within the counterbores; whereby the "adjacent faces of the blocksmay be moved into contact n'itlreach other. At the inner side of the clamp-block the shear-plate 28 is secured thereto, said plate "beiiigsoproportioned and arranged that its inner side is plane as the inner side of the holder blocli and the inner end of the mandrel 20. The upper porupwardly extending lug on the clamp-block 26, and between the same is arranged. the lever 29, which is plvotally connected therewith by means'of yshonldered bolt 30, as

The lever 29' is norfront end with a its rear end being con spring32, the latter exand being connected with a hook 33 at the rear edge of the baseplate. The bar or link 34 is pivotally conhandle 31, and at nected with the lever "29 intermediate the rear end thereof and the pivot-bolt 30. The lower end of said link l-is pivotally con nected with the rear end of the shear-blade 35, Which extends along the inner side of the holder-block 19 and is pivotally connected theretvitlrnear the front end by a screw '36. The thickness of the shear-blade is such that it fits slidably" between the holder-block and the end of the anvil-bar. The upper part of the blade, at the intermediateportion which lies betweenthe ends of the 1nandrel'20and the anyil baryis beveled to form a cutting edge adjoining the mandrel. In said beveled portion of the blade there are two rectangular notches 37 which are alined With the 'igrooyes or reeesses23 of theholder-block, as shownin F 1 7, and between the bevetedged "portion and the pivot-screw 36 the upper dge of theblade is deeply recessedcrcut away, asshoivn, to provide clearance for cer- --tain special forms of stampmrounts sometimes used. i

"l helowei" edge of the shoar-plateQB is slightlyrecessed abore the mandrel 20, as shown in Fig; 7, blockis engaged with the holder-block there will be a sutlicient clearance between the so that when the clamps'hear-plateand mandrel to receive the body tongues tongues chance to be beneath the clan-upb'locldduring the shearing operatioir- As before mentioned, the [described mechanisnr is intended and particularly adapted for applying to the wooden blocks or mounts, eomnionly used for rubber hand stamps, 'label holding channel-bars of the character shown in my (Jo-pending application hereinbefore identified; The stamp-blocks or mounts l) are of ariousuidths and lengths, but are of substai'itially uniform thickness, the latter being approximately the same a: the Width of the channel-barsA. l Handles E'are attached to the central part of the blocks or niountsD, the size of the handles difl'ering but slightly for 'all sizes of the finounts. In the use of the mechanism the ge-pines is employed When a number of the InoiintsDk he same length are" to have the label-holders applied thereto, said pin being placed in one of the holes SSsu h that the mount will be approximately cen- 1 tried with the bumper-bar When the end of the mount 1s engaged with tho gage-pin.

the lateral position of the mountblock with respect to the anvil-bar is gaged by placing the bottom side of the mount-block, or that opposite the handle E, against the front face ot the standard 14, as represented in Figs. 1 and 6. When the stamp or cushion has been attached to the mount-block before the label-holder is applied, the position of the block is reversed from that shown in said figures, the handle E being extended back through the hole 18 in the standard 14, and the position of the block is gaged by the contact between the face of the standard and the top of the block, or the side to which the handle E is attached. Prior to the placing of the mount D beneath the bumper-bar, the channel-bar A is inserted and pushed in along the anvilrbar until its end engages the gage-pin 39, so that when the mount-block is placed thereon said gage-pin serves to accurately register the end of the block with the end of the channel-bar. \Vhile the mount-block is held in gaged position the hand-knob 16 may be sharply struck one or more times to drive the bumpenbar down against the upper edge of the block, and thereby force the latter against the tongues C of the channel-bar, so that said tongues penetrate the mount and become clinched therein, as represented in Fig. 1. Then the mount and the attached channel-bar are moved along the anvi lbar until the end of the mount is engaged with the side of the shear-plate 28, after which the handle 31 of the operating-lever 29 is pushed down. The strength of the springs 21 and 32 is so proportioncd that the initial movement of the lever is about the fulcrum formed by its pivotal connection with the upper end of the link 34, so that the shear-plate 28 and clamp-block 26 are moved downwardly until the latter engages the upper side of the holder-block 19. During such movement, the sharpened lower edge 40 ot the shear-plate will cut. through the tongues C, should any ot the same be located in the shearing-plane, and at the conclusion of this portion of the operation the body of the channel-bar A is confined at all. sides in the shearing-plane, the inside of the channel being filled with the mandrel and its flanges 22, the outer sides of the channel-flanges B being confined by the holder-block l9, and the back or upper side of the channel-bar being confined by the shear-blade. Then by further clownu'ard movement of the handle 31, the lever 25) moves pivotally about the bolt 80, so that the link (A and the rear end of the shearblade are raised thereby; ,As the shearblade is raised the beveled cutting edge thereof shears oi? the entire portion of the channel-bar A which is attached to the mount-block D, and at the same time turns inwardly the corners of the flanges B so as to substantially close the ends of the spaces within said flanges at the sheared end. The turning in of the flange-corners is effected because of the notches 87, which. are solocated that the corners of the cutting edge of the shearblade, at the adjacent sides of the grooves or notches 37, engage the channel-flanges B near the edges thereof, shearing the same and. turning them inwardly before the blade engages and shears cit the remaining body-portion 01' the channel-bar. The main body of the channel-bar A, whicl remains clamped between the holder-block, mandrel, clamp-block, and shear-plate, is preserved in its original sectional torm, because of its being supported at all sides by said members. Thus one end of each piece of the channelbar which is sheared oil is kept open for the insertion of the label therein, while the flanges are turned in at the other end to prevent the label from passing through the channel at said end. The advantage of this will be more clearly apparent when the same is considered in connection with the machine for labelling hand-stamps, disclosed in my companion application filed herewith.

After the operation of the shearing devices to cut off a piece of the channel-bar A, and when the lever 29 is released, the springs 32 and 27 raise the lever and the clamp-block to their normal or initial positions, so that there iselearance above the mandrel for the tongues C to pass the shear-plate 28.when the next section of the channel-bar A is to be pushed out over the anvil-bar.

For applying the label-holders to single mounts, it is unnecessary to set the gage-pin '39, and the mount and channel-bar may be placed'with their ends in register by mere inspection.

When the label-holders are to be applied to mount-blocks which already have the stamp or cushion attached thereto, so that the handle E must be inserted through the opening 18 in the standard as before described, a piece of the channel-bar A of the proper length is first sheared oil? and then slid along the anvil-bar to a position beneath the mount-block before the bumper bar is operated to drive the tongues G into the block and thus attach the channel-bar to the block.

Now, having described my. invention, what I claim and desire to secure by Letters Patent is:
